Our chart of standard sizes lists them all. You can still customise the look and feel of your frame after selecting one of these popular sizes. If the rim is not marked with its bead diameter you can read this from the tyre – it’s the one dimension they have in common.

A very popular set of standard sizes in the UK are the "A" series of paper sizes, such as A4 or A2. We have a handy guide all about "A" paper sizes too. Custom Sizes Carport Direct has conveniently priced a wide selection of Standard and Triple Wide Size Steel Car ports in sizes from 12’ to 30’ wide, & from 21’ to 41’/51’ long, which are suitable for most of our customers. We offer these standard sizes to save you time & money. We can build any custom size in between these sizes. Any custom size is priced the same as the next size up. I.e., a 16′ wide is priced the same as an 18′ wide, a 29′ long would be priced the same as a 31′ long. Why Choose Metal Carport? Well, the answer couldn’t be easier! In the calculator there are many options for each unit of measurement. All tyres are marked with a pressure. Sometimes this is an absolute maximum that nobody should need to exceed, or sometimes only a recommended maximum that may be exceeded by heavier riders (such as tandemists). One way to define it, popular in times past, was to measure the tyre’s outside diameter and its maximum width when inflated, but this can be misleading. For example, some tyres marked 28" are actually much less than 27 inches in diameter, while 26×1.5 and 26×1½ are two completely different sizes.Sometimes you can’t find any ISO size on a tyre, only the old-school markings. Although they’re familiar they can be confusing. Tyres of the same size may come with lots of different markings: 28×1¼×15/8, 28×1¾×1¼ or 700×32C, for example, which are all 32-622.

As far as possible, then, use these columns to convert to ISO dimensions and then have nothing more to do with those old markings! On the other hand it increases the stress on the sidewall of the tyre. Mountain bike tyres are designed to take this extra stress but road tyres are not. There is no industry-wide convention for tubeless tyre fitment and satisfactory results are mostly likely using parts made for use together such as Mavic’s UTS (Universal Tubeless System) tyres and rims. Nevertheless, tubeless-compatible tyres are generally available in the standard 29"/700C/622mmISO, 27.5"/650B/585mmISO and 26"/559mmISO formats. It is inadvisable to use non-tubeless tyres without an inner tube as there is a risk of tyre blow-off. Tubular tyres

Even worse, the same or very similar markings can sometimes be found on completely different sizes of tyre: 26×1½ and 26x1.5. It might be supposed that these two tyres are both notionally 26" diameter and one and a half inches in width, but 26×1½ is a whole inch bigger than 26×1.5.

Standard Imperial 'Inch' picture frame sizes & conversions Standard Metric 'CM' picture frame sizes Two tyres with the same ISO markings are completely interchangeable, even if one seems to be metric and the other is also marked in inches. For example, 650B and 26×1½ are both 38-584 and should be marked accordingly. Look for the ISO numbers and you always know exactly where you are.Standard Imperial 'Inch' picture frame sizes & conversions Standard Imperial'Inch' picture frame sizes The initial two-digit number is the tyre section and roughly indicates the tyre width. Its actual width is normally less, but varies according to how the tyre is designed and the width of rim to which it is fitted. But the height of the tyre usually corresponds quite closely to tyre section, so overall diameter approximately equals the bead diameter plus twice the section.
